How are the atoms of carbon different from the atoms of nitrogen
Per my research, it was said that each of the atoms of the carbon has over 6 protons, six neutrons, and 6 protons. Each atom of nitrogen has 7 protons, 7 electrons, and 7 neutrons. The atomic mass of carbon and nitrogen is 12 and 14 respectively. As the number of electrons in the atoms of the two elements is different they have different chemical properties.
Explanation:As you may know, I did my research and this is what it gave me. I would suppose it is correct since it explains that the carob has over 6 protons and so on. Correct me if I am incorrect and I hope this helped. Have a good one!
(っ＾▿＾)۶٩(˘◡˘ )28g of aluminum reacts with 45g oxygen
1) complete balanced equation?
2) what is the limiting reactant?
3) how many grams of product could be formed?
4) how many grams of excess would you predict?
5) if you actually measured 50g of product, what is the percent yield?
Answer:
answer below:
Explanation:
1) 4 Al + 3 O2 --> 2Al2O3.
2) Al mol= 28/27 = 1.037mol
O mol= 45/16 = 2.812mol
Al : O
4 : 2
x : 2.812
cross multiply
4 x 2.812/2 = 5.624 mol of Al
Al is limiting reactant
3) 28/5.246 = 5.34product can be formed (not that much sure)
4) 45/ 0.5185 = 86.79
86.79 - 5.34 = 81.45g
5) 50 / 81.45 x 100 = 61.39% ( i guess)
i hope this hleps you

6. What type of energy is the result of water and hot matter interacting?
Boiling water on a stove is an example of thermal energy. Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.
what is nucular decay
Answer:
Nuclear decay is also called radioactive decay, and it occurs in a series of sequential reactions until a stable nucleus is reached. Nuclear reactions release much more energy—orders of magnitude more—than exothermic chemical reactions.

When the equation H2 + Fe3O4 = Fe + H2O is completely balanced using the smallest whole numbers, the coefficient oH2 would be A.) 1 B.)2 C.) 3 D.) 4
Answer:
H2 would have a coefficient of 2.
Explanation:
According to the balanced chemical equation, the coefficient of hydrogen is 4.
What is chemical equation?Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Explanation:
Cells are made of many parts, or , that help the cell do its job. Each cell organelle has a specific function, or
Answer:
Organelles; role.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;
1. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.
2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.
3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Chromosomes : they give sets of instructions for the synthesis of products.
5. Ribosomes : they are involved in the build up of proteins.
6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.
7. Cytoskeleton : they help to maintain and support the shape of the cells.
8. Vesicles : they ensure proteins are properly transported to the right and exact location.
9. Golgi apparatus : it prepares the protein for export by chemically tagging them.
10. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
Hence, cells are made of many parts, or organelles, that help the cell do its job. Each cell organelle has a specific function, or role.

What is the pH of 0.12M HNO3
Answer:
pH= 0.92
Explanation:
HNO3-> H^+ +NO3^-
HNO3 is a strong acid, so it fully dissociates
[HNO3] = 0.12M [H^+] = 0.12M
pH= -log[H^+]
pH=-log[.12] = 0.92
pH = 0.92

The partial pressures of CH4, N2, and O2 in a sample of gas were found to be 248 mm Hg, 707 mm Hg, and 518 mm Hg, respectively. What is the mole fraction of Nitrogen gas?
total pressure=248+707+518=1473mmHg
partial pressure=total pressure×mole fraction
mole fraction of N2
=partial pressure of N2/total pressure
=707mmHg/1473mmHg
=0.4800
